Joylashtirilgan bilan Kador

High-quality emeralds should be bright and pure emerald green. Variety of yellow, blue, gray, brown and other variegated tones will reduce the color quality of emeralds; grandmothers with uniform color, uneven color or lighter color are required Green, its price is also lower. Bunga qo'chimcha, due to the production environment, emeralds are very rich in inclusions and cleavage is very developed. Shu sababli, emeralds with high purity and large particles are especially valuable and their value will increase significantly. High-quality emeralds often use an emerald-type cut.

In addition to emeralds, the most precious beryl is aquamarine. High-quality aquamarine should be pure, bright, dense, clean, shaffof, cut in the correct proportions, and polished. Unlike emeralds, large, uncracked aquamarines are relatively easy to obtain.

Identification of emeralds and aquamarine:

Gemstones similar to emeralds include green tourmaline, green apatite, chrome diopside, emerald, garnet, va hokazo. Emeralds and their distinguishing methods can be easily identified after detailed measurement of physical and chemical properties such as refractive index, birefringence, and absorption spectrum. Masalan, the pleochroism of green tourmaline is very strong, and the after-cut edge ghosting is obvious. The hardness of green apatite is lower than that of emeralds. The green of chromium diopside is dark, without the green velvet feeling of emerald, and the refractive index is higher than that of emerald.

Jade is an interwoven structure of variable phenocryst crystal fibers, which is an aggregate. Emerald is a single crystal, heterogeneous body, there are four bright and four dark phenomenon under the polarizer.

Demantoid garnet is a homogeneous body, and horsetail-like asbestos inclusions are common inside. Green garnets often have a yellow hue, no pleochroism, relative density, and the same size is relatively heavy.

The gems similar to aquamarine include blue topaz and blue sapphire. Their refractive indices are obviously different, and they are easy to distinguish after detailed identification.

Natural emeralds are the closest to synthetic emeralds, and identification is difficult. The identification of natural emeralds and synthetic emeralds is mainly based on typical inclusions; emeralds of different synthetic methods and natural emeralds also have differences in refractive index, birefringence, and density, and can also be done with the help of large instruments Identification.
